Windows: Padding a string before assigning?

To get the text of the foreground window, you can do this:

Code: Select all

fg=getforegroundwindow_() : t$=Space(255) : getwindowtext_(fg,t$,255)

However, I've noticed that this also works:

Code: Select all

fg=getforegroundwindow_() : getwindowtext_(fg,t$,255)

So is there any actual requirement to pad t$ first? I know it creates a
buffer for the text, but if it works without it, what's the problem?

UAR! What are you doing there?? )
It works, but you do not allocate memory for your use. It is possible that these section of mem is allready in use by another task and it would be fatal to write datas to a random memory position.
This should work too, but you shoul NEVER use it:
fg=getforegroundwindow_() : getwindowtext_(fg,rnd(5000000),255) )))

Please alloc some mem first and other tasks will thank you.

So by setting t$ to Space(255), this is allocating the memory for it, right?
That's what I've been doing all along, and if that's the right way, then I'll
keep doing it.
